What is CVE-2026-111449?
CVE-2026-111449 is a medium-severity vulnerability in Wheels, published on 16 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Wheels 3.0.0 through 4.1.1 can disclose detailed exceptions when allowIPBasedDebugAccess=true (disabled by default). An allowed administrator request changes error/debug-display settings in shared application scope. If it overlaps with an unauthorized client's request that raises an error, that client can receive full exception details, including tag context or a serialized exception, and any sensitive data they contain. This race does not bypass the production gate protecting developer tools. This is fixed in 4.1.2.
Weakness: CWE-362
